Question

find the value of x and y in following figure ​

Answer 1

This would be the detailed explanation

Answer 2

Step-by-step explanation:

According to angle sum property of a triangle,

70+80+y=180

150+y=180

y=180-150

y=30

Because y and x points lie on straight line

30+x=180

x=180-30

x=150

even according to rule,

X=Sum of 2 opposite angles

we can derive x=70+80

x=150.
